TO ALL WHOM IT MAY CONCERN Be it known that we, SNAI/i' JAMES BEST, of 193 Bermondsey street, in the county of Surrey, and JAMES JOHN HOLDEN, of 6 Single street, Bow, in the county of Middlesex, both in the United Kingdom of Great Britain, have invented a. new and useful Machine or Apparatus for Charging and Drawing Gas Retorts, and for other like purposes. l v

Our invention relates more particularly to the manufacture of coal gas, and consists of apparatus or machinery for economizing the laborand cost of, and time. occupied in, charging the retorts with coal and i withdrawing the coke therefrom. With this apparatus or machines all the retorts in oiie oven or set can he charged by one operation, and the coke withdrawn. therefrom also at one operation. And 'we do hereby declare that the following is a. full, clear, and exact description of the same, reference being made, first, to the accompanying geometrical scale drawings A and B, making parts of this specification, and showing the apparatus and machines by plan section and elevation; and secondly, to the accompanying drawings, C, D, and E, upon which the machines are shown in model form, those' parts of the apparatus which appear upon all the drawdngs being lettered with similar letters. l

The forms and modes of constructing the said machines are thus fully illustrated upon the accompanying drawings, and explained in the following reference applying thereto, and the mode of using the same is hereinafter fully described. l

Explanation of the Drawings.

Figure 1 shows a front view of two sets of gas retorts, and the charging apparatus 'applied thereto, and also'shows the feeding stage for supplying the charging-scoops with coals. y

Figure 2 is a transverse section through the centre oth'e retorts, and shows the two side elevationfof the charging-apparatus At A the latter is shown in position for entering the retorts, and at B as inserted therein.

Figure 3 is a plan of the retorts at the horizontal centre line' thereof, and shows the charging apparatus;

alsoin plantovcr all) the. position of the apparatus at C corresponds with that shown at A, iig. 1, and at D, as shown at B, iig. l, with the charging-scoop inserted in the retorts, and turned bottom upwards, in which reversed position the coals being deposited in the retorts) the scoops are withdrawn. The following reference applies to each of these figures where the respective index letters and figures appear: a the retorts, b the charging-scoops.

Figure 4 shows the form of the scoops in transverse section at E F, iig. 3, as charged and inserted in a. retort; and

Figure 5, the same scoop reversed, and the coals deposited. The curved line 1, 1 shows the form of the lip or end of the scoop, which is partly cut away or made hollow, so Athat it may pass 'over without touchingthe deposited coals as the discharge-scoop is withdrawn. l

c c c are railways. or tramways, along which the charging and drawing apparatuses are propelled, in which d d are turn-tables; c is a. horizontal platform frame ot' angle iron, mounted. upon the travelling-wheelsf; g is a vertical frame working in slides in the horizontal frame, across which it has a. traversing motion fromp to z', and vice versa; k the shafts of the scoops, which. together therewith, turn in'hearings 2 and in the smalltoothed wheels 3 in vertical fra-me. These wheels rotate upon short axes or shafts,`which are each traversed by a square hole to receive the ends of the scoop-shafts, which shafts each terminate withv a screw fastened with a nut in front. By slacking one or more of these nuts, one or more'of the scoopsA can he readily detached, when required. 4 are vertical racks, which gear or couple or engage with the toothed wheels 3, and are raised and lowered (and thereby reverse the position of the scoops) by the lever 5, shaft 6, and rack and pinion (or wheel and chain) motion 7 und 8. The end of the lever is held secure in its vertical position by a notch at 10, and thus prevents the scoops and coals from turning over until the lever is moved. 11 11,are two strong side grooves, plancd true to receive two rails ortongues which are fined to the bottom of the verticalframe, and upon which it slides and is supported. 12 is an endless chain, attachedy to and by which the sliding-frame is moved backwards and forwards. This chain is driven by turning the wheel 13. The entire apparatus can be moved and worked by hand, ii` required; but we propose to fit it with, asmall engine, and connect the engineshaft by common wheel-work with the Aaxle or axles of the travelling-wheels und with the endless-chain wheels, so as to both move and work the machine thereby; the engine, dto., being similar to that here shown, or of any vother form and arrun gement suitable for the purpose. In order to facilitt the operation of this machine and that of the drawing machine hereinafter described, and which forms a. parto'f tli pparat'us, we propose, in the erection of new gas-works, or in. putting in new retorts, to form the latter in the shape of truncated cones, ,the mouthat each en d being slightly larger than the centre; und, in order to facilitate the opening andl closing of those and the ordinary retorts, wc propose to fit the covers in fram es,'or suspend '.them, so that the whole of the covers to oneset ci: retorts could be.' raised and lowered, and therefor-ts opened and closed simultaneously or singly. The mode of accomplishing-this is shown at iig. 1.k ,At G (drawingA) the covers are iitted to the sliding upright bai-5145, slack'ed from and tightencdngainstthe mo'uth oftheretort bythe screws 15 in the-centre. The eentreicfover is here shown as removedtoone side. All the covers being movable, in thisway, each'retort can bev opened,clmr'ged,zand closed singly keeping the covers in tbcirfnormal position; and, raising th'e frame bodily,` the wholevofsthe rctorts can be' opened or closed' at one ,operation. -1G` are strong side-plates, behind which the main frame slids;"17',-.b`alance weights. .The covers atlare balanced in a similar way, and all rise together,v or can be each raised and removed singly. "These-v eoversare suspended -from the cross-bar 17* by ehains, .havingeach, dra\ v, =pin', 18 which` pin, when taken out, releases the cover from the set. 19 is a -revolving bar, the two ends of which'aiwedgeshaped, and when turned, slide in behind notches in projecting pieces 20 at the side of the retort vflange. Zlare centre-screwsffor urthergtightening theeovers against the retort mouth. For supplying the charging-.scoops quickly and respeetivelywith therequiredlquantity of coals, we propose to.A construct a'fcharging-stageor stages, having a number of .grooved openings vor perforations to correspond' with the number of scoops." 'These' 'openings orperforations'form troughs er holders for gauging t l. `the required quantity of coal. The bottoms o f these troughs are each niovable, being made to open downwards by'tipping,fdropping, sliding, or turning upon an axis, andare each iitted with tubes or'conduits for conducting and discharging thecoals'int the-'chargin'g-scoopa the latter being' placed under them for that purpose. One `offthesecharging-stages, fitted withtippingfseoopais'shown partly in elevation and partlyfin section at fig. 1. f l.. u are the scoops, which are filled with'v coalsfrom the, coal heap;l @the tubes orrcondui'ts'; "w, short pins or centres l, in' thb'er'rds` ot'` the-scoops, upon which they turn over or tip;":'n,toothed wheels'iixed thereto land vengaging with eachothcr'jy, lever:andwlieelfor'tipping the scoops when filled. By placing these stages'atV the ends of the` ranges 'of retorts, and lin n. linetherewith, thechaiging-scops are run under them'by the traversing motion of the vertical frame, ,each scoop'can thusbeXinStantly.supplied with the exact. quant-ity of coals required; `which-quentity can bcgangedlor regulatorias before described, or'by-weighing or otherwise'from the stage above. l

Anienlarged section of," n tippiiigA-scop-and stage bottom is shown at g. 6.l Thedrawing'.machine consists of a-n'umbe'r of L hoes', rakes, or scrapers, the blades of which rise to'arh'orizestal', and"fallto-averticali'positionfon hinges.v The'ar'ms or Ihandles are mounted upon a horizontal and travelling platform fra1ne,"botl1 framesbeing similar to those of the =charging-machine, to, with, and by which the drawing'mahinefxean be attached, moved, and worked, or separately, and by hzilnd'iThe arms of the drawing' fakes or'- serapers are and' areftraversed artid' fr'r'aising 4the blades'to a horizontal position, so as to pass above the coke as they enter 4theretcrts, .anditcllowerfthenftoa vertical' position behind the coke ,has they are withdrawn fromthewretorts. The arms are formed with joints in vertical frame, so that the ends'whichicarry the blades can alsobe raisedand: lowered, as required. They are, further, so mounted and A i fitted that both armsand'blades canbemadevtoturn upon their horizontal axes by rackand pinion motion,
